A grinding device for a bell-shaped cutter (10) of a scarfing machine has a rotating grinding disc (20) which can be adjusted by means of a servo drive (24) in the direction of a rotating cutting edge (14) of the L-shaped cutter (10). In order to prevent the grinding disc (20) from coming to rest against the cutting edge (14) in an abrupt fashion, which would lead to the formation of dents or notches on the cutting edge (14), means are provided for detecting the torque (M) of the grinding disc (20), which means block further displacement of the grinding disc (20) when a predetermined adjustment value of the torque (M) is exceeded. <IMAGE>
